Fast forward from the YR1 to the mercifully cleaner lines of the 1970 R5 350. Adding new seven-port, reed-valve cylinders and a few other refinements turned the '72 R5C into the 1973 RD350. Now we're on to something. Even in '73, RD styling was still parked somewhere between tawdry and garish. But 0.010-inch thick spring steel reed valves between 28mm carburetors and the new, seven-port cylinders made all the difference. The 347cc RD twin used classical 64x54 bore and stroke numbers to spin out about 35 horses at 7500 rpm.

The RD350's street roots stretch back to February 1967, and the YR1--Yamaha's first street-legal 350. But the 1970 R5 350 drew a straight line from brand Y's TR production racers to the street.
